ABSTRACT
The Railway Reservation System facilitates the passengers to enquire about
the trains available on the basis of source and destination, Booking and
Cancellation of tickets, enquire about the status of the booked ticket, etc. The aim
of case study is to design and develop a database maintaining the records of
different trains, train status, and passengers.
This project contains Introduction to the Railways reservation
system .It is the computerized system of reserving the seats of train seats in
advanced. It is mainly used for long route. On-line reservation has made the
process for the reservation of seats very much easier than ever before.
In our country India, there are number of counters for the reservation of
the seats and one can easily make reservations and get tickets. Then this project
contains entity relationship model diagram based on railway reservation system
and introduction to relation model .There is also design of the database
of the railway reservation system based on relation model. Example of some SQL
queries to retrieves data from rail management database.

INTRODUCTION
Database is an organized collection of data. The data is typically organized
to model aspects of reality in a way that supports processes requiring information.
A DBMS makes it possible for end users to create, read, update and delete data in a
database. The DBMS essentially serves as an interface between the database and
end users or application programs, ensuring that data is consistently organized and
remains easily accessible. The DBMS manages three important things: the data, the
database engine that allows data to be accessed, locked and modified and the
database schema, which defines the database’s logical structure. These three
foundational elements help provide concurrency, security, data integrity and
uniform administration procedures. The DBMS can offer both logical and physical
data independence. That means it can protect users and applications from needing
to know where data is stored or having to be concerned about changes to the
physical structure of data.
The main purpose of maintaining database for Railway Reservation System
is to reduce the manual errors involved in the booking and cancelling of tickets and
make it convenient for the customers and providers to maintain the data about their
customers and also about the seats available at them.Due to automation many
loopholes that exist in the manual maintenance of the records can be removed. The
speed of obtaining and processing the data will be fast. For future expansion the
proposed system can be web enabled so that clients can make various enquiries
about trains between stations. Due to this, sometimes a lot of problems occur and
they are facing many disputes with customers. To solve the above problem, we
design a data base which includes customer details, availability of seats in trains,
no of trains and their details.

PROJECT DESCRIPTION
This project is about creating the database about Railway Reservation System.
The railway reservation system facilitates the passengers to enquire about
the trains available on the basis of source and destination, booking and cancellation
of tickets, enquire about the status of the booked ticket, etc. The aim of case study
is to design and develop a database maintaining the records of different trains, train
status, and passengers. The record of train includes its number, name, source,
destination, and days on which it is available, whereas record of train status
includes dates for which tickets can be booked, total number of seats available, and
number of seats already booked.
Passengers can book their tickets for the train in which seats are available.
For this, passenger has to provide the desired train number and the date for which
ticket is to be booked. Before booking a ticket for a passenger, the validity of train
number and booking date is checked. Once the train number and booking date are
validated, it is checked whether the seat is available. If yes, the ticket is booked
with confirm status and corresponding ticket ID is generated which is stored along
with other details of the passenger. The ticket once booked can be cancelled at any
time. For this, the passenger has to provide the ticket ID (the unique key). The
ticket ID is searched and the corresponding record is deleted. With this, the first
ticket with waiting status also gets confirmed.
List of Assumption Since the reservation system is very large in reality, it is
not feasible to develop the case study to that extent and prepare documentation at
that level. Therefore, a small sample case study has been created to demonstrate

the working of the reservation system. To implement this sample case study, some
assumptions have been made, which are as follows:
1. The number of trains has been restricted to 5.
2. The booking is open only for next seven days from the current date.
3. Only two categories of tickets can be booked, namely, AC and General.
4. The total number of tickets that can be booked in each category (AC and
General) is 10.
5. The total number of tickets that can be given the status of waiting is 2.
6. The in‐ between stoppage stations and their bookings are not considered.
List of trains has to be maintained. Detailed Passenger information is to be
maintained In the booking procedure, the train number, train date, and category are
read from the passenger. On the basis of the values provided by the passenger,
corresponding record is retrieved from the Train_Status. If the desired category is
AC, then total number of AC seats and number of booked AC seats are compared
in order to find whether ticket can be booked or not. Similarly, it can be checked
for the general category. If ticket can be booked, then passenger details are read
and stored in the Passenger table. In the cancellation procedure, ticket ID is read
from the passenger and corresponding record is searched in the Passenger. If the
record exists, it is deleted. After deleting the record (if it is confirmed), first record
with waiting status for the same train and same category are searched from the
Passenger table and its status is changed to confirm.

CONCLUSION
In our project Railway reservation system we have stored all the information about the Trains
scheduled and the users booking tickets and even status of trains, seats etc. This data base is
helpful for the applications which facilitate passengers to book the train tickets and check the
details of trains and their status from their place itself it avoids inconviniences of going to
railway station for each and every query they get. We had considered the most important
requriments only, many more features and details cand be added to our project inorder to obtain
even more user friendly applications. These applications are already in progress and in future
they can be upgraded and may become part of amazing technology.
